Benefit scroungers have been pilloried for ages.
In your original list, the only one which anybody has any control over is the smokers. I certainly wouldn't want to go back to the time when every Pub and cafe stuck of cigarette smoke and every table had its overflowing ashtray.
I too am a little on the "cuddly" side and apart from not really having enough room in Economy on my rare visits abroad, I haven't really noticed any discrimination. But, just like the smokers, I could alter that if I desired.
